    Cutting a bike frame so BBSHD can fit higher up?

    I love everything about the BBSHD except for how much it hangs down below the bottom bracket. I'm constantly having clearance issues where I can't ride over logs and rocks without banging on the BBSHD shell. It's gotten so bad that I'm considering major modifications to my bike just to get...

    Accidentally left Cycle Analyst on overnight, drained my batteries to death?

    Here's the situation: I rode my ebike over the weekend, used about 75% of the battery and then stored the bike away, but i forgot to unplug my battery / turn off the ignition to the controller, which left the Cycle Analyst screen on. When I checked the bike about 24 hours later, the screen was...

    Recommended charger for 12s, 4.1 per cell (49.2V)?

    I'm looking for a charger for my 12s 48V 10Ah battery pack. I only want to charge to 4.1v per cell for better longevity, so 49.2V final voltage. Anyone know of a charger like this, or one I could modify to get the voltage I need? It's a lipo pack so I wouldn't mind higher charge rates, 5A or...

    Custom genesis v2100 torque arm

    This is my plan for a genesis V2100 torque arm with clamping dropouts and disc brake adapter mounting holes. It would be much easier to get it waterjet cut, but the goal is to use the tools that I have in my garage and some 1/4" thick steel 4"x12" that I have lying around. The purple marker is...

    Help with fixing my controller's broken throttle function?

    My controller just stopped working randomly one day. I've done some troubleshooting and I think the problem is something is wrong with the throttle function. I tested the throttle wires with a multimeter and they read 0 volts, both when connected to the throttle and disconnected. The manual that...

    Battery in backpack vs. mounted to frame

    Anyone use a backpack for their batteries instead of mounting them to your bike frame? I've been toying with the idea of using a backpack since a lot of the bikes I would want to convert to electric don't really have a suitable space in the frame to mount a battery. See: freeride bikes and...

    Upgrading my controller and battery, suggestions?

    This is my first e-bike build and my first post on E-S. I've been lurking for a while for advice and I built my first bike thanks to some helpful threads around here. I have an xcceries 1000W 48V kit from ebay. I believe this kit is similar but probably not the exact same...
